Truck has had trouble starting not catching. after several seconds of engine turning over and pumping the accelerator, there was no fuel smell, first checks would be the relay or filter but I don't know where they are. it is an S10 crew cab
fuel system on 2003 Chevrolet S10
Chances are the fuel pump in your 2003 Chevrolet S10 is failing. Your first step should be to check the fuel pressure. The fuel pressure should be 55 - 62 psi with the fuel pump running and the engine off.
